Abstract

PURPOSE: To make the look of a garden made on a concrete floor such as on a flat roof attractive at its peripheral fence walls and improve the operability for fence wall formation. CONSTITUTION: The concrete floor 1 is covered with a rooting inhibitor sheet 2 and the frame F is set along the periphery of the garden. The frame 7 comprises the base 11 and cover 12 having U-shaped cross sections which can be fitted to each other. The fence is controlled in its height by the fitting degree of the cover 12. The bases 11 opposing to each other is prevented from becoming wider in their space width using binders 14 and the strings 13. In the space inside the frame F, an air exhaustion mat 2a, water drainage mat 3 and a vegetation mat 3 are placed and lawn 4 or the like is planted and water is properly is fed from the water pipe 6 in the mat 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame which surrounds a garden constructed on a flat roof floor surface of a building or the like and a concrete surface such as a veranda, and performs shape retention around the garden.

[0002]

[Technical background] In the urban areas where the green areas have decreased while living has become rich, in order to harmonize the city with nature, not only the surrounding area of the building but also the rooftop of the building, concrete such as a veranda, etc. On the floor, there is a garden where plants such as grass, plants and flowers are planted.

In this garden, as shown in FIG. 3, a root-preventing sheet 2 is laid on a concrete floor surface 1 of a flat roof, a drainage ventilation mat 2a is laid thereon, and then a plurality of layers of vegetation mat 3 are laid, On top of that, turf 4 etc. are planted,
This circumference is surrounded by a frame F. The plants such as the turf 4 are supplied with water from the water distribution pipe 5 in the frame F to the porous water supply pipe 6 in the vegetation mat 3.

As shown in FIG. 4, the water is supplied to the water distribution pipe 5 from an automatic water supply device 7 which automatically operates based on the amount of water in the vegetation mat 3, and is supplied through each porous water supply pipe 6. The water supply control is performed by the control panel 8, and unnecessary water is discharged through the electric valve 9.

[0005]

In the garden on the concrete floor surface 1, the conventional frame F, as shown in FIG. 3, has U-shaped members 20 and 21 fitted sideways, and bolts and nuts 22 are used. It is fixed.

The frame F formed of the members 20 and 21 has an unsatisfactory appearance because the end face of the member can be seen from the outer side, and tightening with the bolts and nuts 22 is troublesome. Further, since both members 20 and 21 are made of a hard material such as FRP, it is difficult to process them when cutting an edge measure or the like. For preventing sagging, a steel rod or the like is passed between the opposing frames F, but this work is troublesome.

In view of the above points, the present invention aims to improve the appearance of the peripheral side surface of the garden and to improve the workability of mounting the frame forming the peripheral side surface.

[0008]

In order to solve the above-mentioned problems, in the invention according to claim 1, a vegetation mat 3 is installed on a concrete floor surface 1 such as a flat roof floor surface. A frame F surrounding the vegetation mat 3 in a garden where plants such as turf 4, garden trees, and flowers are planted, and has the following configuration.

The concrete floor surface 1 is provided with a base 11 having an upward U-shaped cross section, and a cover 12 having a downward U-shaped cross section fitted into the base 11 from above.

The base 11 and the cover 12 are preferably made of a soft plastic such as polypropylene or vinyl chloride mixed with a tensile fiber (claim 2).
The base 11 is preferably provided with a sagging prevention tool 14 (claim 3).

[0011]

The garden frame F according to the present invention thus constructed is constructed by fixing the base 11 along the periphery of the garden and fitting the cover 12 to the base 11. At this time, if the locking tool 14 is provided, it is difficult for the base 11 to drape,
If the base 11 and the cover 12 are made of soft plastic, they can be easily cut.

[0012]

[Effect] The present invention is constructed as described above and exhibits the following effects through the above operations.

Since the fitting is performed in the vertical direction, the frame F can be easily assembled.

If the base 11 and the cover 12 are made of soft plastic or if the locking tool 14 is provided, the work is easy.

Since the outer peripheral surface is the side surface of the cover 12, the outer peripheral surface is a substantially flat surface, which is good in appearance and excellent in design.

Since the upper surface of the base 11 is open, piping into the base 11 is easy.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a frame F according to the present invention comprises a base 11 having an upwardly U-shaped cross section and a cover 1 having a downwardly U-shaped cross section which is fitted into the base 11 from above.
It consists of 2. The base 11 and the cover 12 are extruded products made of vinyl chloride resin or the like.
The length is appropriately determined according to the size of the garden, and the number of types is also appropriate.

The cover 12 is a claw 11 at the lower end of the base 11.
By similarly fitting the lower end claw 12a and the middle concave portion 12b to the a and middle convex portion 11b, they are prevented from coming off, and the height is adjusted by moving them up and down as shown by the chain line in FIG. The adjusted position of the cover 12 is maintained by the fitting friction with the base 11.

In this frame F, as shown in FIG. 1, a root-preventing sheet 2 is laid on a concrete floor surface 1, a base 11 is fixed along the periphery of a garden space, and a cover 12 is fitted on the base 11. Configure. At this time, the locking tool 14 stretched with the string 13 is hooked on the claw 11a at the lower end at an appropriate position between the opposing bases 11 to prevent the garden width from expanding and prevent the base 11 from sagging. The string 13 may be omitted if it is not spread. Further, the water distribution pipe 5 is appropriately arranged in the base 11.

After the frame F has been formed on the periphery, the drainage ventilation mat 2a is laid in the same manner as in the conventional case, and then the required number of vegetation mats 3 are laid, on which turf 4, flowers, trees and the like are vegetated. . The drainage ventilation mat 2a is formed by laminating a sheet having protrusions on the lower side of the porous sheet. Porous water supply pipes 6 are provided at appropriate places in the vegetation mat 3, and water from the automatic water supply device 7 is appropriately sent from the pipes 6 into the vegetation mat 3.
